Division mechanism of labor in Diqing Tibetan Pigs gut microbiota for dietary fiber efficiently utilization.

The Diqing Tibetan (TP) pig is an roughage tolerance breed that inhabits an area with the highest altitude distribution in the world and can be maintained on a diet containing 90 % forage material in confined production systems. Our results showed that TP pigs had a strong capability for high-efficiency utilization of arabinose and xylose. Metagenomic analysis revealed that the secretion of carbohydrate esterases was mainly undertaken by fecal strains of Microbacterium, Alistipes, Acinetobacter, and Faecalibacterium, while Microbacterium, Prevotella, Turicibacter, Lactobacillus, Clostridium, and Streptococcus were responsible for most of the secretion of glycoside hydrolases.

Flavor properties of post-heated fermented milk revealed by a comprehensive analysis based on volatile and non-volatile metabolites and sensory evaluation.

Existing research on the post-heating processing of fermented milk has primarily focused on single post-heating treatments and the texture, while research on how changes in metabolites during different post-heating treatments affect flavor and sensory properties is limited. This study investigates the changes in volatile metabolites in fermented milk treated at different post-heating temperatures to determine the characteristic aroma types and analyzes the changes in non-volatile metabolites associated with aroma-active compounds or their precursors to clarify the causes of the altered flavor and sensory properties. The results showed that in the 65 °C and 75 °C treatments, 63 volatile compounds were produced by Strecker degradation, lipid oxidation and esterification to produce ketones and aldehydes.

Ultrasound-assisted low-sodium salt curing to modify the quality characteristics of beef for aging.

Meat products for elderly people are high in sodium content and hardness. Thus, the aim of this study is to explore how ultrasound-assisted low-sodium salting improves meat quality and determine the conditions that result in meat tenderness ideal for people aged 65-74 years. The ultrasound-assisted treatment of bovine hip muscle with non-sodium salt (CaCl and CHCaO) was adopted, followed by sous vide (SV) cooking (65 ℃ for 8-12 h).

Bidirectional "Win-Win": Asymmetrical Nanobowl-Coupled Aggregation-Induced Emissive Nanosilicon-Enhanced Immunochromatographic Strips for the Ultrasensitive Detection of .

The lack of nanoprobes with an efficient signal response and overlook of cooperation between nanoprobes can be responsible for the unsatisfactory analytical performance of immunochromatographic strips (ITSs). Herein, asymmetrical nanobowl-confined innumerable gold nanoparticles (AuNPs) (AuNPs@AFRNBs) to enhance the light absorption are developed for quenching the fluorescence of aggregation-induced emissive (AIE) nanosilicons, which is used for the construction of a bidirectional complementary-enhanced ITS (BC-ITS) to ultrasensitively detect (). Briefly, density functional theory-screened AIEgens with highly fluorescent brightness are confined in nanosilicons, and the nanoconfinement has improved the fluorescent brightness by 6.

Frequency and Genetic Analysis of Porcine Circovirus Type 2, Which Circulated between 2014 and 2021 in Jiangsu, China.

Porcine circovirus-associated diseases, caused by porcine circovirus type 2 (PCV2), are widespread and result in significant economic losses to the global swine industry. PCV2 can currently be divided into nine genotypes (PCV2a to PCV2i), with the currently dominant one being the PCV2d genotype. In this study, 2675 samples from 804 pig farms in 13 cities in Jiangsu Province, China, were collected between 2014 and 2021 and subjected to polymerase chain reaction analysis to investigate the frequency and genetic diversity of PCV2.

More sensitive microbial responses to the interactive effects of warming and altered precipitation in subsoil than topsoil of an alpine grassland ecosystem.

Subsoil is a large organic carbon reservoir, storing more than half of the total soil organic carbon (SOC) globally. Conventionally, subsoil is assumed to not be susceptible to climate change, but recent studies document that climate change could significantly alter subsoil carbon cycling. However, little is known about subsoil microbial responses to the interactive effects of climate warming and altered precipitation.
